New hope for young cancer patients: glofitamab trial targets tough lymphoma
NCT ID NCT05533775
First seen Jun 25, 2026 · Last updated Sep 04, 2026 · Updated 6 times
Summary
This study tests a drug called glofitamab, which helps the immune system find and kill cancer cells, in children and young adults (ages 6 months to under 30) whose B-cell lymphoma has come back or not responded to treatment. Some participants receive glofitamab alone, while others get it combined with standard chemotherapy. The goal is to see if the drug is safe and can shrink or eliminate tumors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- glofitamab (a drug that helps the immune system attack cancer cells), given alone or with standard chemotherapy (rituximab, ifosfamide, carboplatin, etoposide)
- What this could lead to
- If successful, this could provide a new treatment option for children and young adults with hard-to-treat B-cell lymphoma, potentially improving remission rates.
- What could go wrong
- This is an early-phase trial (Phase 1/2) with only 65 participants, so results may not apply to everyone. Side effects from the drug or chemo could be serious, and the treatment may not work for all.
This is an AI summary of the original study and may miss details. Read our disclaimer.

Inclusion Criteria: * Age 6 months to \< 18 years at the time of signing Informed Consent for Cohort A Part 1 and Cohort B of the study, and age 6 months to \< 30 years old at the time of signing Informed Consent for Cohort A Part 2 of the study * Histologically re-confirmed diagnosis, via tissue biopsy, or bone marrow aspirate, pleural effusion, or ascites, prior to study entry of aggressive mature B-NHL that expresses CD20 (reconfirmed by IHC or flow cytometry if IHC is not possible), including BL, BAL (mature B-cell leukemia FAB L3), DLBCL, and PMBCL, at the time of first R/R disease for Cohort A and second or greater R/R disease for Cohort B * Refractory or relapsed disease (i.e., prior treatment was ineffective or intolerable) following first-line standard-of-care chemoimmunotherapy for Cohort A and following at least two prior systemic chemoimmunotherapy regimens and who have exhausted all available established therapies for Cohort B * Measurable disease, defined as: At least one bi-dimensionally measurable nodal lesion, defined as \> 1.5 cm in its longest dimension, or at least one bi dimensionally measurable extranodal lesion, defined as \> 1.0 cm in its longest dimension; or percentage of bone marrow involvement with lymphoma cells defined by cytomorphological analysis of bone marrow aspirates * Adequate performance status, as assessed according to the Lansky or Karnofsky Performance Status scales: Participants \< 16 years old: Lansky Performance Status ≥ 50%; Participants ≥ 16 years old: Karnofsky Performance Status ≥ 50% * Adequate bone marrow, liver, and renal function * Negative test results for acute or chronic hepatitis B virus (HBV), hepatitis C virus (HCV) * Negative HIV test at screening, with the following exception: Individuals with a positive HIV test at screening are eligible provided they are stable on anti-retroviral therapy for at least 4 weeks, have a CD4 count ≥200/uL, have an undetectable viral load, and have not had a history of opportunistic infection attributable to AIDS within the last 12 months * Negative SARS-CoV-2 antigen or PCR test within 7 days prior to enrollment * Participants and/or caregivers who are willing and able to complete clinical outcome assessments throughout the study using either paper or interviewer methods Exclusion Criteria: * Isolated CNS disease of mature B-NHL without systemic involvement, and primary CNS lymphoma * Receipt of glofitamab prior to study enrollment * Ongoing adverse events from prior anti-cancer therapy that were not resolved to Grade ≤ 1 (exceptions: alopecia, Grade 2 peripheral neuropathy) * Grade ≥ 3 adverse events, with the exception of Grade 3 endocrinopathy managed with replacement therapy * Participants with active infections which are not resolved prior to Day 1 of Cycle 1 * Prior solid organ transplantation * Known or suspected history of hemophagocytic lymphohistiocytosis (HLH), or chronic active Epstein-Barr viral infection (CAEBV) * Active autoimmune disease requiring treatment * History of severe allergic or anaphylactic reactions to monoclonal antibody therapy (or recombinant antibody-related fusion proteins) or known sensitivity or allergy to murine products, except if the participant was able to safely receive it after initial administration (consider consultation with Medical Monitor) * History of confirmed progressive multifocal leukoencephalopathy * Current or past history of uncontrolled non-malignant CNS disease, such as stroke, epilepsy, CNS vasculitis, or neurodegenerative disease * Evidence of significant and uncontrolled concomitant diseases that could affect compliance with the protocol or interpretation of results * Major surgery or significant traumatic injury \< 28 days prior to the obinutuzumab pretreatment infusion (excluding biopsies) or anticipation of the need for major surgery during study treatment * Administration of a live, attenuated vaccine within 4 weeks before the start of study treatment (obinutuzumab pretreatment) or at any time during the study treatment period and within 12 months after end of study treatment * Participants with any other diseases, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that would contraindicate the use of an investigational drug
